To a/ZZ whom it mayv concern:

Be it known that We, FERRISL. R. FRAN- oisoo and JAMES C. Tiroir, citizens of the United States, residing at New York, in the county and State of New York, have invented a new and useful Concrete Insert, of which the following is a specification.

This invention relates to an improvement in concrete inserts.

In the construction of concrete buildings, particularly that class in which reinforced concrete is used, it is necessary to' insert devices from which pipes or shafting may be suspended. This 1s usually done during the constructipn of the buildin to avoid the necessity for. drilling the har( ened concrete afterward. Certain devices have been employed for this purpose but these devices' are objectionable for the reason that they are frequently displaced when the `concrete vis poured into the forms and when so displacedI ecome practically useless. i y It is one of the objects of this inventionl t'oV provide a concrete insert having means for` preventin its displacement during the oper-I ation oi iil ing the forms.

A further object of the invention is toA provide a device of this character Which may be anchored to the reinforcing bars.

Still another object is to provide a device b of this character constructed of sheet metal bent to suitable form whereby the initial cst of the device -is decreased.

With this and other objects'in view, the invention consists incertain constructions which will be hereinafter fully described and i then specically set forth in the claims hereunto appended.

Referring to thevdrawings4 which forni a part of this specification and in which like characters of referenceA indicate the saine parts, Figure 1 is a plan view of ablank from which an insert is formed; Fi 2 is a side elevation of a formed 'insert ustrating one method of holding the device in position during the operation of filling the forms Fig. 3

planes at right angles to the axi'sof the"4v In carrying-the invention into effect, an

insert l,is employed which is provided with means for holding it in position during the operation of filling the forms and this 'means may vary widely in character. v

1n the device selected to illustrate the invention, the .holding means are integral with the insert and consist of wings extended from one or from both ends of the body of the in- .4 sert and arranged to contact with the wooden form in which the concrete is poured.

In the best constructions and as shown, there is rovideda sheet metal blank 1, so shaped tii .bent to form a bod portion 2, having flari y ortion- 2 is provide with a slot 4 arrangedP to receive a bolt-head 5, ,to which pipes or shafting ma be secured.

at the main section thereof may be f The edges of the blank alonglt eslot 4 are bent upwardly, as is clearly s own in Fig. 3,

of providing a double bolt-head 5 rests. or the purpose of holding the body porposition during the operation insert is provided with wings 6 which rest upon the form and provide an extended ase to prevent the upsetting of the insert when the concrete is thro'wn in the inold. In the best construotionsfand as shown, -the wings 6 are also arran with the reinforcing barsv 7. en the reinforcing bars lie parallel tothe axis of the ed to contact 'l insert, the wings 6 are extended at rightangles to the axis of the body portion `2, but

when 'the reinforcing bars lie at right angles to the axis oi the insert, thewings 6 are bent so that they lie parallel to the axis 'of the body portion 2, as is clearly shown in 6.

Means are provided for anchoring the iii- ,V sert to the reinforcing bars so that the barsthemselves will be caused to carry a ortion of the load on the bolt and insert. or this purpose, in the best constructions and as shown, there are provided extensions '8 andjj 9 rising from the end Wall of the insert, and these extensions vmay be bent over anail or, barlying across two or more of the reinorcing bars 7, as clearly shown in Figs. 4. and 5.

ltwill be readily understood thatwhen the blank has been bent tov form the insert andl has been anchored to the reinforcing bars IIo that there can be no. displacement of the insert when the concrete is poured into the mold. Furthermore, the insert When an-l chored to the reinforcing bars serves to space the latter from the formsI thus obviatingr the .necessity of providing independent Vs for this pur ose.

It Wil readily be understood also that the o eration of' bending up the .Wings of the b ankinto the position shown in Figs. 2, 4 and 6 closes the 'ends of the body portion 2- so that'the concrete cannot flow into the interior of the insert. It will be readily understood also that, after the extensions 8 have been bent to 'their proper position and the concrete oured into the inold and allowed to harden,v it will be impossible for any part ofthe device to move.

Changes and variations may be made in the structure by means of which the invent'ion is carried into effect. The invention therefore is not to be restricted to the precise structure shown anddescribed.

What is claimed is v 1. A.) concrete hanger insert constructed I fof sheet metal comprising a `body portion havin a plurality of extended Wings arrange to be bent to anchor the insert to the reinforcing bars, substantially as described.

semis 2. A concrete hanger insert constructed of sheet metal comprising a. slotted hollow bod y portion having daring sides and extended nnchoring` wings, substantially ns described.

3. A concrete hanger insert comprising a slotted hollow body portion having flaring sides and extended anchoring Wings, sul stantially as described.

4. A concrete hanger insert constructed o.' sheet metal formed from a single blank and having a. slotted body portion and extended anchoringr wings, substantially as described.

5. A concrete henger insert coi'istrncted of sheet metal comprising a slotted hollow body portion having wings extended therefroin arranged to be bent to anchor the insert `to the reinforcing bers, substantiallyas described. I
